Objectives Gingival phenotype is closely related to treatment success and aesthetic results in the maxillary anterior region. Several methods were proposed to measure the dimensions of the gingival tissue. This study aimed to evaluate the gingival thickness using clinical and radiographic techniques and to explore the association between gingival thickness and gingival phenotypes classified by color-coded phenotype probes. Materials and methods The gingival thickness of 86 periodontally healthy maxillary anterior teeth was assessed using transgingival probing (TGP) and cone-beam computed tomography (CBCT). The gingival phenotype was classified as thin, medium, thick, or very thick by transparency of the color-coded probes through the gingival sulcus. The labial alveolar bone thickness was measured on CBCT images. The keratinized tissue width (KTW) was recorded. Results Good to excellent agreement was found between TGP and CBCT regarding the thickness of the gingiva (p<0.001). There was a very high correlation between the phenotypes determined by color-coded probes and the gingival thickness measured by TGP (r=0.953, p<0.001). KTW was significantly higher in thick and very thick phenotype groups compared with thin phenotype group. Conclusion Cone-beam computed tomography images and the probe transparency method with color-coded probes are reliable for identifying the gingival phenotype in the maxillary anterior region, based on comparisons to direct transgingival probing.

Changes in the macro and trace element composition of saliva might be indicative for pathological changes in periodontal tissues. However, there is a lack of evidence in the literature showing associations between mineral elements and periodontal status. The aim of this study was to determine whether such associations occur. Totally, 190 systemically healthy non-smoker participants (mean age 32.2 +/- 6.02; 50 periodontally healthy, 50 gingivitis, 50 chronic periodontitis, and 40 aggressive periodontitis individuals) were included in this cross-sectional study. Salivary levels of some macro and trace elements were measured by using inductively coupled plasma mass spectrometry (ICP-MS). Kruskal-Wallis's test was used for statistical analysis. Statistically significant differences were found in sodium (Na), magnesium (Mg), potassium (K), calcium (Ca), vanadium (V), chromium Cr), manganese (Mn), iron (Fe), rubidium (Rb), strontium (Sr), and selenium (Se) concentrations among the groups. Significant increases in the essential minerals Na, Mg, K, Ca, Fe, and Se occurred in both periodontitis groups when compared to the gingivitis and periodontally healthy groups. Lower Se, Sr, Fe, Mn, and V concentrations were found in the aggressive periodontitis group than in the chronic periodontitis group. The results of this study demonstrated that assessment of mineral element concentrations in saliva might be useful in assessing periodontal health and disease. However, further studies are required to determine whether the change in a specific mineral element is the result of periodontal disease or is involved in its pathogenesis.
Prevalence of Carotid Artery Calcification on Digital Panoramic Radiographs in Hemodialysis Patients on Kidney Transplant Waiting List
(2021) Inonu, Elif; Yilmaz, Mediha Nur Nisanci; Orhan, Kaan; Ozemre, Mehmet Ozgur; Ogutcu, Nagehan Burcu; Kal, Oznur; https://orcid.org/0000-0001-6768-0176; 34387149
Objectives: The detection of carotid artery calcification at an early stage is important to reduce the effects of cardiovascular disease in patients undergoing hemodialysis. This study sought to evaluate the prevalence of carotid artery calcification from panoramic radiographs of patients who were undergoing hemodialysis and to assess the relationship between such calcification and certain medical and periodontal parameters. Materials and Methods: We evaluated 120 panoramic radiographs from patients who were undergoing hemodialysis for the presence of carotid artery calcification. Full-mouth periodontal clinical and medical parameters were recorded, and patients were diagnosed on the basis of the new periodontal disease classification. Patient medical records from the same period (the same week) during which the panoramic radiographs were taken were also assessed. Results: Among the 120 participating patients, panoramic radiographs from 27 patients (22.5%) showed a uni- or bilaterally radiopaque mass. Of the periodontal clinical parameters investigated for associations between patients with and without carotid artery calcification, there was only a significant difference shown for probing pocket depth (P =.017). No significant differences were found between the groups with and without carotid artery calcification with regard to any other medical or periodontal parameter. Conclusions: In our study group, suspected carotid artery calcifications were detected on panoramic radiographs in about one-fourth of total patients receiving hemodialysis. Because of the significant relationship found between probing pocket depth and carotid artery calcification, the presence of periodontal disease may be associated with calcifications in these patients. Dentists should maintain awareness in detecting these lesions when evaluating panoramic radiographs of patients undergoing hemodialysis.
Salivary Del-1, IL-17, and LFA-1 levels in periodontal health and disease
(2020) Inonu, Elif; Kayis, Seyit Ali; Eskan, Mehmet Akif; Hakki, Sema S.; 32153040
Objective and Background Developmental endothelial locus-1 (Del-1), lymphocyte function-associated antigen-1 (LFA-1), and interleukin 17 (IL-17) play critical roles in transendothelial migration of neutrophils in periodontal diseases. The aim of this study was to evaluate salivary Del-1, IL-17, and LFA-1 protein levels in patients with gingivitis (G), chronic periodontitis (CP), and generalized aggressive periodontitis (GAP). Methods A total of 180 systemically healthy, non-smoking patients (45 periodontally healthy (H) and 45 G, 50 CP, and 40 GAP) individuals (between March 2014 and February 2016) were included in this study according to Armitage's (1999) classification. Clinical periodontal parameters, including clinical attachment level, probing depth, plaque index, and gingival index, were recorded. Del-1, IL-17, and LFA-1 protein expression levels were measured in unstimulated saliva samples collected from patients by using enzyme-linked immunosorbent assays.Kruskal-WallisandMann-Whitney U testswere used for multiple comparisons and post hoc statistical analyses, respectively. ROC curve analysis was used to evaluate the sensitivity and specificity of Del-1, IL-17, and LFA-1 in distinguishing periodontal disease from health and gingivitis. Results It was found a high level of IL-17 and a low level of Del-1 in the CP and GAP, as compared to the G and H groups (P < .001). Nevertheless, we found LFA-1 levels were higher in the GAP than in the CP or G groups (P = .00). Consistently, LFA-1 levels were lower in the H and G groups than in the CP and GAP groups (P = .00). The combination of three biomarkers was found as the best predictor yielded exhibited the highest AUC [0.893, 0.845-0.94 (%95 CI)P < .001] in discriminating periodontal disease from health and gingivitis. Conclusion Salivary Del-1, LFA-1, and IL-17 levels might be useful markers for determining the clinical health and disease status of patients with periodontitis. However, further studies that evaluate the level of salivary Del-1, LFA-1, and IL-17 before and after periodontal therapy are required to understand the exact roles of these cytokines during the periodontal healing period.
